Active Directory sites are intended to enhance network performance through effective management of replication and authentication across diverse locations. However, researchers from Synacktiv have revealed that these management tools can be weaponized by malicious actors to initiate severe attacks. Exploiting permissions such as GenericAll, GenericWrite, and WriteGPLink on site objects, attackers can gain unauthorized control to inject harmful Group Policy Objects (GPOs) that impact all linked systems, allowing for a quick escalation to domain administrator privileges.
The exploitation of Active Directory sites poses significant threats as it facilitates lateral movement across entire forest infrastructures. Malicious GPOs can be linked to site configurations, compromising domain controllers and bypassing standard security safeguards such as SID filtering. This attack vector represents a critical vulnerability within many organizations, undermining existing security frameworks and potentially allowing attackers to move freely across domains. Organizations are encouraged to revise their permissions management strategies and strengthen defenses against this overlooked exploitation pathway.
